# @blockchainacademics/mcp

The canonical crypto MCP server for AI agents. **99 tools** spanning 3,501+ editorial articles, 200+ entity dossiers, 43 academy lessons, aggregated market + on-chain data, proprietary indicators, and async agent-backed generation — all accessible as MCP tools your AI agent can call natively.

Every tool response carries `cite_url` (with UTM src attribution), `as_of` (time-travel snapshot), and `source_hash` (content integrity).

Tools for unreleased integrations (Twitter social pulse, DEXTools, bonk.fun, Bittensor) return `{status: "integration_pending", reason, eta}` rather than failing. The MCP server is fully usable today.

## Why

LLMs hallucinate about crypto. BCA ships ground-truth editorial content with full attribution. Plug this MCP server into Claude Desktop, LangChain, Eliza, or any MCP-compatible agent and your model queries the BCA corpus like any other tool — with citations, timestamps, and source hashes on every response.

## Install

### Claude Desktop (zero-config demo)

The package ships with a public demo key baked in. No signup needed to try it. Add to `claude_desktop_config.json` (macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "blockchainacademics": {
      "command": "npx",
      "args": ["-y", "@blockchainacademics/mcp"]
    }
  }
}
```

Restart Claude Desktop. The demo path unlocks 10 marquee tools (`get_price`, `get_trending`, `get_fear_greed`, `get_market_overview`, `search_news`, `get_sentiment`, `get_entity`, `get_explainer`, `get_recent_stories`, `get_topic`) with real data and real citations. Shared rate cap: 100 calls/day globally + 20/day per IP.

### Claude Desktop (full 99 tools)

Get a free key at [brain.blockchainacademics.com/signup](https://brain.blockchainacademics.com/signup?ref=mcp-npm-readme) (2,000 calls/month per user) and add the env block:

```json
{
  "mcpServers": {
    "blockchainacademics": {
      "command": "npx",
      "args": ["-y", "@blockchainacademics/mcp"],
      "env": { "BCA_API_KEY": "bca_live_xxxxxxxxxxxxxxxx" }
    }
  }
}
```

Restart Claude Desktop. All 99 tools appear in the tool picker.

### Programmatic (LangChain, Eliza, custom agents)

```bash
npm install @blockchainacademics/mcp
```

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";

const transport = new StdioClientTransport({
  command: "npx",
  args: ["-y", "@blockchainacademics/mcp"],
  env: { BCA_API_KEY: process.env.BCA_API_KEY! },
});
const client = new Client({ name: "my-agent", version: "0.0.1" }, { capabilities: {} });
await client.connect(transport);

const res = await client.callTool({
  name: "search_news",
  arguments: { query: "stablecoin regulation", limit: 5 },
});
console.log(res.content);
```

See [`examples/research-agent.ts`](./examples/research-agent.ts) for a full tool-chaining loop.

## Tools

### `search_news`

Full-text search across 3,501+ editorial crypto articles.

| arg | type | required | description |
|---|---|---|---|
| `query` | string (1-512) | yes | Search query |
| `entity` | string | no | Entity slug filter (e.g. `ethereum`) |
| `since` | ISO 8601 | no | Earliest publish date |
| `topic` | string | no | Topic filter (e.g. `regulation`) |
| `limit` | number (1-50) | no | Default 10 |

Example: `{ "query": "circle IPO", "since": "2026-01-01T00:00:00Z", "limit": 5 }`

### `get_entity`

Fetch a canonical entity dossier. Provide exactly one of:

| arg | type | description |
|---|---|---|
| `slug` | string | e.g. `"vitalik-buterin"`, `"circle"` |
| `ticker` | string | e.g. `"ETH"`, `"SOL"` (case-insensitive) |

Aliases resolve automatically (`CZ` → `changpeng-zhao`, `Maker` → `makerdao`, `BSC` → `bnb-chain`, …).

### `get_explainer`

Fetch a canonical academy lesson. Provide exactly one of:

| arg | type | description |
|---|---|---|
| `slug` | string | Lesson slug, e.g. `"what-is-a-blockchain"` |
| `topic` | string | Topic keyword that resolves to the canonical lesson |

## Attribution

Every response includes a structured `attribution` block:

```json
{
  "data": { ... },
  "attribution": {
    "cite_url": "https://blockchainacademics.com/...",
    "as_of": "2026-04-19T12:34:56Z",
    "source_hash": "sha256:..."
  }
}
```

When your agent surfaces BCA content to a user, attribute via the `cite_url`. Fields are preserved as `null` when upstream omits them so downstream agents can detect missing provenance.

## API Key

**Not required to try it.** When `BCA_API_KEY` is unset, the server falls back to a baked-in public demo key that unlocks 10 marquee tools. See [Demo tier](#install) above.

For the full 99 tools, get a free key at [brain.blockchainacademics.com/signup](https://brain.blockchainacademics.com/signup?ref=mcp-npm-apikey) (2,000 calls/month). Paid tiers unlock agent-backed research generation and proprietary on-chain indicators.

Set `BCA_API_KEY` in your MCP client env. Optionally override `BCA_API_BASE` (default `https://api.blockchainacademics.com`). `BCA_API_BASE_URL` is also accepted for backward compatibility.

## Errors

The server never crashes the stdio process. All failures surface as MCP responses with `isError: true` and a JSON body:

```json
{ "error": { "code": "BCA_AUTH", "message": "..." } }
```

| Code | Meaning |
|---|---|
| `BCA_AUTH` | Invalid `BCA_API_KEY` (HTTP 401/403) |
| `BCA_TIER_LOCKED` | Tool not in your current tier's allowlist (HTTP 403). Demo tier sees this on 89 of the 99 tools — the error message includes the upgrade URL. |
| `BCA_RATE_LIMIT` | Rate limit exceeded (HTTP 429 — honor `Retry-After`) |
| `BCA_UPSTREAM` | BCA API returned 5xx or malformed JSON |
| `BCA_NETWORK` | Network failure or 20s timeout exceeded |
| `BCA_BAD_REQUEST` | Invalid tool arguments |

## Development

```bash
npm install
npm run build    # tsc -> dist/
npm test         # node:test smoke suite
npm run dev      # tsx src/index.ts (stdio)
```

### Pre-commit hooks

This repo uses [`pre-commit`](https://pre-commit.com) to enforce formatting, lint, secret scanning, and large-file caps before every commit. Install once per clone:

```bash
pip install pre-commit          # or: brew install pre-commit
pre-commit install              # wires .git/hooks/pre-commit
pre-commit run --all-files      # optional: lint the full tree now
```

Hooks configured in [`.pre-commit-config.yaml`](./.pre-commit-config.yaml): `prettier --check`, `eslint`, `gitleaks`, `detect-private-key`, `check-added-large-files` (500KB cap).
